The object of the ancient initiations being to ameliorate mankind and to perfect the intellectual part of man, the nature of the human soul, its origin, its destination, its relations to the body and to universal nature, all formed part of the mystic science; and to them in part the lessons given to the Initiate were directed. For it was believed that initiation tended to his perfection, and to preventing the divine part within him, overloaded with matter gross and earthy, from being plunged into gloom, and impeded in its return to the Deity. The soul, with them, was not a mere conception or abstraction; but a reality including in itself life and thought; or, rather, of whose essence it was to live and think.

It was material; but not brute, inert, inactive, lifeless, motionless, formless, lightless matter. It was held to be active, reasoning, thinking; its natural home in the highest regions of the Universe, whence it descended to illuminate, give form and movement to, vivify, animate, and carry with itself the baser matter; and whither it unceasingly tends to reascend, when and as soon as it can free itself from its connection with that matter. From that substance, divine, infinitely delicate and active, essentially luminous, the souls of men were formed, and by it alone, uniting with and organizing their bodies, men lived.

This was the doctrine of Pythagoras, who learned it when he received the Egyptian Mysteries: and it was the doctrine of all who, by means of the ceremonial of initiation, thought to purify the soul. Virgil makes the spirit of Anchises teach it to Æneas: and all the expiations and lustrations used in the Mysteries were but symbols of those intellectual ones by which the soul was to be purged of its vice-spots and stains, and freed of the incumbrance of its earthly prison, so that it might rise unimpeded to the source from which it came.

Hence sprung the doctrine of the transmigration of souls; which Pythagoras taught as an allegory, and those who came after him received literally. Plato, like him, drew his doctrines from the East and the Mysteries, and undertook to translate the language of the symbols used there, into that of Philosophy; and to prove by argument and philosophical deduction, what, felt by the consciousness, the Mysteries taught by symbols as an indisputable fact,—the immortality of the soul. Cicero did the same; and followed the Mysteries in teaching that the Gods were but mortal men, who for their great virtues and signal services had deserved that their souls should, after death, be raised to that lofty rank.

It being taught in the Mysteries, either by way of allegory, the meaning of which was not made known except to a select few, or, perhaps only at a later day, as an actual reality, that the souls of the vicious dead passed into the bodies of those animals to whose nature their vices had most affinity, it was also taught that the soul could avoid these transmigrations, often successive and numerous, by the practice of virtue, which would acquit it of them, free it from the circle of successive generations, and restore it at once to its source. Hence nothing was so ardently prayed for by the Initiates, says Proclus, as this happy fortune, which, delivering them from the empire of Evil, would restore them to their true life, and conduct them to the place of final rest. To this doctrine probably referred those figures of animals and monsters which were exhibited to the Initiate, before allowing him to see the sacred light for which he sighed.

Plato says, that souls will not reach the term of their ills, until the revolutions of the world have restored them to their primitive condition, and purified them from the stains which they have contracted by the contagion of fire, earth, and air. And he held that they could not be allowed to enter Heaven, until they had distinguished themselves by the practice of virtue in some one of three several bodies. The Manicheans allowed five: Pindar, the same number as Plato; as did the Jews.

And Cicero says, that the ancient soothsayers, and the interpreters of the will of the Gods, in their religious ceremonies and initiations, taught that we expiate here below the crimes committed in a prior life; and for that are born. It was taught in these Mysteries, that the soul passes through several states, and that the pains and sorrows of this life are an expiation of prior faults.

This doctrine of transmigration of souls obtained, as Porphyry informs us, among the Persians and Magi. It was held in the East and the West, and that from the remotest antiquity. Herodotus found it among the Egyptians, who made the term of the circle of migrations from one human body, through animals, fishes, and birds, to another human body, three thousand years. Empedocles even held that souls went into plants. Of these, the laurel was the noblest, as of animals the lion; both being consecrated to the Sun, to which, it was held in the Orient, virtuous souls were to return. The Curds, the Chinese, the Kabbalists, all held the same doctrine. So Origen held, and the Bishop Synesius, the latter of whom had been initiated, and who thus prayed to God: "O Father, grant that my soul, reunited to the light, may not be plunged again into the defilements of earth!" So the Gnostics held; and even the Disciples of Christ inquired if the man who was born blind, was not so punished for some sin that he had committed before his birth.

Virgil, in the celebrated allegory in which he develops the doctrines taught in the Mysteries, enunciated the doctrine, held by most of the ancient philosophers, of the pre-existence of souls, in the eternal fire from which they emanate; that fire which animates the Stars, and circulates in every part of Nature: and the purifications of the soul, by fire, water, and air, of which he speaks, and which three modes were employed in the Mysteries of Bacchus, were symbols of the passage of the soul into different bodies.

The relations of the human soul with the rest of nature were a chief object of the science of the Mysteries. The man was there brought face to face with entire nature. The world, and the spherical envelope that surrounds it, were represented by a mystic egg, by the side of the image of the Sun-God whose Mysteries were celebrated. The famous Orphic egg was consecrated to Bacchus in his Mysteries. It was, says Plutarch, an image of the Universe, which engenders everything, and contains everything in its bosom. "Consult," says Macrobius, "the Initiates of the Mysteries of Bacchus, who honor with special veneration the sacred egg." The rounded and almost spherical form of its shell, he says, which encloses it on every side, and confines within itself the principles of life, is a symbolic image of the world; and the world is the universal principle of all things.
